If sin =5/7 x in quadrant I, then find the exact answers for the following (without finding x):
sin(2)=
cos(2x) =
tan(2x)=

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

idk
